Abstract or Introduction

As the demand of energy is increased the oil and gas industry is continuously trying to develop innovative technologies which will be used to increase the production of oil and gas in future. Besides many enhanced oil recovery techniques are present, the sandstone acidizing has been significantly developed to contribute to the petroleum industry. In sandstone acidizing different acids and their combination are applied on the formation. This results in minimizing the near wellbore damage and improve the well productivity. In this project we have performed acidizing on the sandstone rock of Ranikot formation which is present in the Lower Indus Basin. Drilling machine with different drill bit sizes are used to obtain different core samples from the formation rock. We applied HCl and HF acid, and their combination on the sandstone rock. In this project we observed the sandstone acidizing mechanism with different acids and observed problems that occurs due to the application of different acids on the formation. The laboratory results shows that the acidizing perform well when we use the mud acid which is the combination of HCl and HF acid. In the case of HCl acidization, most of the sandstone rock samples completely dissolve in the acid recipe and lose the bulk volume. But in the case of HF acidizing the rock cannot dissolve in the solution but precipitation takes place.
